python turtle绘画 有没有办法加载一幅画作为背景？

[lkf181]

我想要的背景比较复杂，如果都用代码绘制有点太复杂了......... 比如：我想在世界地图上根据实时数据绘制绘制热点等

turtle.bgpic(r'res/bg.png') #这样设置。

下面是方法的介绍：
def bgpic(self, picname=None):
"""Set background image or return name of current backgroundimage.

Optional argument:
picname -- a string, name of a gif-file or "nopic".

If picname is a filename, set the corresponding image as background.
If picname is "nopic", delete backgroundimage, if present.
If picname is None, return the filename of the current backgroundimage.

Example (for a TurtleScreen instance named screen):
>>> screen.bgpic()
'nopic'
>>> screen.bgpic("landscape.gif")
>>> screen.bgpic()
'landscape.gif'
"""
if picname is None:
return self._bgpicname
if picname not in self._bgpics:
self._bgpics[picname] = self._image(picname)
self._setbgpic(self._bgpic, self._bgpics[picname])
self._bgpicname = picname

谢谢，不过加载过来图片会缩小，又是个麻烦事儿........
